NR HEADSET MANUAL
ANR Instruction: The Active Noise Reduction ANR Headset is a
headset that can isolate, offset and cancel noise. In comparison with
passive headsets, it can, under noisy circumstances, provide a
quieter and more comfortable sensation, by reducing background
noise. Therefore, make it possible to improve the audio quality and
articulation, resulting in a higher operation safety factor. The noise
cancelling circuitry reduces outside noise considerably more than a
standard headset, making it more comfortable for the pilot in the
aircraft.
Prepare the headset for Use
1. Rotate the flexible boom overhead to wear the microphone on either
the right or left side of the head.
2. Rotate the headset volume control (on the side of the battery box)
down to the minimum position, before the headset plug is inserted into
the aircraft or intercom.
3. With the headband resting securely on the top of the head, check that
the ear seals are centered over the ears.
4. For best noise cancellation, position the microphone in front of your
lips.
5. Insert the microphone plug (PJ068) into the aircraft or intercom
microphone jack. Insert the earphone plug（PJ055）into the aircraft or
intercom earphone jack.
6. Volume Adjustment Procedure: Rotate the volume control up to a
comfortable level.
7. Auxiliary (AUX) audio input: Insert the plug (3.5mm plug) of your
external audio device into the AUX jack on the side of battery box as
indicated. The volume is controlled by your audio device.
8. Bluetooth function: as indicated in operation 5.
